Genuine OEM Mitsubishi EVO 7/8/9 Left Rear Floor Sidemember – MR592799

Firstly, Buy Mitsubishi EVO 7/8/9 left rear floor sidemember MR592799. Restore the structural integrity of your Mitsubishi Lancer Evolution with the Mitsubishi EVO 7/8/9 left rear floor sidemember – MR592799. This is a genuine OEM Mitsubishi body-structure component designed for the rear floor and chassis area of CT9A Evolution models. Mitsubishi catalogs identify MR592799 as “SIDEMEMBER, RR FLOOR, LH”, with component/PNC 65157L. Specialist Mitsubishi Evo suppliers list the part for Evolution VII, VIII, and IX applications.

The rear floor sidemember is an important part of the vehicle’s underlying body structure. Unlike exterior trim or cosmetic panels, this component forms part of the chassis and rear floor construction. For an Evo that has suffered corrosion, accident damage, previous repairs, or long-term exposure to moisture, replacing a compromised structural panel with the correct OEM component can be an important part of a proper restoration.

Mitsubishi EVO 7/8/9 Left Rear Floor Sidemember – MR592799

The Mitsubishi EVO 7/8/9 left rear floor sidemember is cataloged as MR592799 and carries the Mitsubishi component number 65157L. Parts catalogs identify it specifically as the left-hand rear floor sidemember.

The Evo 7/8/9 CT9A chassis uses a combination of floor panels, crossmembers, extensions, side members, reinforcements, and other welded body components to create the vehicle’s rear underbody structure. Mitsubishi’s Evolution body documentation identifies the rear floor sidemember as one of the structural components of the vehicle underbody.

For restoration work, having the correct panel available is particularly useful because structural repairs need to follow the original body design and mounting geometry as closely as possible.

Genuine OEM Mitsubishi Structural Component

MR592799 is a genuine Mitsubishi OEM replacement panel rather than a universal aftermarket repair section. Nengun lists the part as a genuine Mitsubishi OEM Sidemember, Rr Floor, Lh, while Ross Sport identifies it as a genuine Mitsubishi chassis leg assembly for Evo 7–9.

Using a genuine OEM panel can be valuable when carrying out a detailed restoration because the replacement component is produced around Mitsubishi’s original body architecture. This is especially relevant for Evo owners restoring a vehicle to an original or factory-style specification.

Left-Hand Rear Floor and Chassis Location

The MR592799 is the left-hand rear floor sidemember. Its corresponding right-hand component is cataloged separately, with MR592800 identified as the right-hand rear floor sidemember. Mitsubishi parts catalogs list the two components under PNC 65157L and 65157R, respectively.

This makes accurate identification important when ordering. Left and right structural panels are not interchangeable, and the correct side should be confirmed before purchasing.

Ideal for Evo 7, Evo 8 and Evo 9 Restoration

The Mitsubishi EVO 7/8/9 left rear floor sidemember is particularly relevant for CT9A restoration projects. Specialist Evo suppliers list MR592799 for the Evolution VII, VIII, and IX, while OEM catalogs associate the part with CT9A floor and body applications.

This makes the part suitable for a variety of restoration and structural repair situations, including:

• Rust repair and corrosion restoration
• Rear chassis restoration
• Accident-damaged CT9A repair
• Rear floor structural repairs
• Long-term Evo 7/8/9 restoration projects
• OEM body reconstruction
• Replacement of damaged or heavily corroded original panels
• Factory-style chassis repair

Because this is a structural body component, installation should be performed by a qualified body repair or chassis specialist familiar with welded automotive structures.

Why Replace the Rear Floor Sidemember?

A damaged or corroded rear floor sidemember can compromise the condition of the surrounding body structure. Rust can develop in areas that are difficult to see from outside the vehicle, particularly underneath the car where road moisture, dirt, salt, and debris can accumulate.

Firstly, MR592799 provides the correct OEM Mitsubishi part number for the left-hand rear floor sidemember.

Secondly, the component is specifically associated with CT9A floor construction, making it useful when restoring an Evolution VII, VIII, or IX chassis.

Thirdly, using a genuine replacement structural panel allows a professional repairer to work with an OEM-designed component rather than fabricating an entire replacement section from unrelated material.

Structural Restoration of a Mitsubishi Evo

The rear floor of the CT9A is made up of multiple interconnected structural panels. Mitsubishi’s body repair documentation includes dedicated rear floor replacement procedures, showing that structural repair work involves defined cutting and replacement areas rather than simply bolting on an exterior body panel.

For this reason, MR592799 should be treated as a structural repair component. Installation may involve removal of damaged material, accurate positioning of the replacement panel, welding, corrosion protection, and inspection of the surrounding structure.

Before beginning any structural repair, the vehicle should be properly supported and measured as necessary to ensure that the body remains correctly aligned. Professional installation is strongly recommended.

Check Fitment Before Ordering

Although MR592799 is widely listed for CT9A Evolution applications, Mitsubishi catalogs can contain multiple revisions and related floor-structure part numbers. For example, catalogs list MR592799 as the left rear floor sidemember and MR592800 as the corresponding right-hand component, while other Mitsubishi part numbers can appear in related Lancer/CT9A body catalogs.

For that reason, buyers should verify the chassis number, model year, market, and existing body configuration before ordering. Nengun and other OEM suppliers likewise recommend checking the specific vehicle compatibility rather than relying solely on general model-year information.
